This is a problem particularly when using a DirectShow source, since the real-time buffer will almost immediately fill and cause dropped frames/out of sync audio making it impossible to stream from a live video source.įirst sample, showing the issue, notice the poor fps (input framerate is 59.94 fps) and real-time buffer errors causing frame drops, CPU usage is 40% or lower.Ĭmd> ffmpeg -rtbufsize 902000k -f dshow -r 60000/1001 -video_size 1280x720 -pixel_format uyvy422 -i video='Decklink Video Capture':audio='Decklink Audio Capture' -vcodec libx264 -vf 'unsharp=5:5:0.2:5:5:0.0' -preset medium -profile main -maxrate 1600k -bufsize 2000k -s 960x540 -pix_fmt yuv420p -acodec aac -strict -2 -ab 96k -ar 44100 -af 'volume=3' -f flv -y 'hd.flv' -vcodec libx264 -vf 'unsharp=5:5:0.2:5:5:0.0,fps=fps=30' -preset medium -profile main -maxrate 900k -bufsize 2000k -s 854x480 -pix_fmt yuv420p -acodec aac -strict -2 -ab 96k -ar 44100 -af 'volume=3' -f flv -y 'sd.flv'įfmpeg version N-66809-g20df026 Copyright (c) 2000-2014 the FFmpeg developersĬonfiguration: -enable-gpl -enable-version3 -disable-w32threads -enable-avisynth -enable-bzlib -enable-fontconfig -enable-frei0r -enable-gnutls -enable-iconv -enable-liīass -enable-libbluray -enable-libbs2b -enable-libcaca -enable-libfreetype -enable-libgme -enable-libgsm -enable-libilbc -enable-libmodplug -enable-libmp3lame -enable-lib If only used on one of the two outputs, performance appears normal.

For a full list of GPUs and formats supported, please see the available GPU Support Matrix.Summary of the bug: When using FFmpeg to encode two seperate video outputs from a single video source, performance drops significantly when using the 'unsharp' video filter on BOTH outputs. Ability to add your own custom high-performance CUDA filters using the shared CUDA context implementation in FFmpeg.Create high-performance end-to-end hardware-accelerated video processing, 1:N encoding and 1:N transcoding pipeline using built-in filters in FFmpeg.Granular control over encoding settings such as encoding preset, rate control and other video quality parameters.Hardware-accelerated decoding of H.264, HEVC, VP9, VP8, MPEG2, MPEG4*, and AV1.

Hardware-accelerated encoding of H.264 and HEVC*.

If you have an NVIDIA GPU which supports hardware-accelerated video encoding and decoding, it’s simply a matter of compiling FFmpeg binary with the required support for NVIDIA libraries and using the resulting binaries to speed up video encoding/decoding.įFmpeg supports following functionality accelerated by video hardware on NVIDIA GPUs:
